TEL AVIV — Israeli Prime Minister Benjamin Netanyahu says his side have paid a "heavy price" for the war in Gaza; following one of its deadliest weekends of fighting so far.

Remarking on the latest numbers of Israeli troop deaths, Netanyahu said that the war in Gaza was exacting a "very heavy price" as the death toll mounted over the weekend.

Netanyahu he said his forces would continue with "full force until the end", reiterating his goal to eliminate Hamas and ensure the safe return of hostages held in Gaza.

"Let it be clear: this will be a long war," the Israeli prime minister added.
